European Part Approval

European Part Approval

European Part Approval (EPA) refers to parts that are produced in accordance with approved design data which is not property of the type certificate holder, except for European Technical Standard Order (ETSO) parts. EPA marked parts should not be equated with PMA (Part Manufacturing Approval) marked parts under the FAA system, as these are two different concepts.

EPA is defined by:

Commission Regulation (EU) No 748/2012 of 3 August 2012 laying down implementing rules for airworthiness and environmental certification of aircraft and related products, parts and appliances, as well as for the certification of design and production organisations (SL L 224 21.8.2012).
